Abstract: Solid Oxide Fuel Cells (SOFCs) offer a high potential for application as an auxiliary power unit (APU) for heavy goods vehicles as well as combined heat and power (CHP) sysems. SOFCs are estecially attractive due to their high efficiencies and th use of different fuel types. However, otimization in terms of long term stability and costs are still necessary. This work characterized the degradation of SOFCs with lanthanum strontium manganite (LSM) cathodes under chromium influence. Galvanostatic cell tests were carried out at 800$^{\circ}$C with operation times from 250 - 3000 h and variation of the chromium source ans current density. The current densities of j = 0 A/cm$^{2}$, j = 0,3A/cm$^{2}$ and j = 0,5 A/cm$^{2}$ were applied. the high temperature ferritic alloy Crofer22APU was used as a chromium source. Variation of the chromium source was realized by coating the Crofer22APU insert with the chromium retention layer Mn$_{3}$O$_{4}$ and the cathode contact layer LCC10. [...]
